I am not a techie person, but this tutorial really did the trick— who knew this could be done at home? My suggestions: do this when you won’t be distracted and have plenty of time. Read through the directions step by step, and the comments, before you start, so you can know the pitfalls on each step in advance. The tools worked really well- no need for anything from home, other than a can of soda, rubber band, and hair dryer (heat really does help with the adhesive strips; mine both broke and I had to use the card technique to remove the old battery). I also used a magnetic sheet magnet (the kind you get for the fridge with a calendar or ad on it) to hold the tiny screws, with post-its indicating which step they were associated with. Good luck!
